POWERSIL® 466 A/B is suitable for production of electrically conductive injection moulded articles, especially cable accessories in the medium and high voltage range. The range of use spreads from push-on accessories to cold shrink applications. POWERSIL® 466 A/B combines a low Shore A durometer with high elongation, good setting properties (low tension set) and good mechanical properties which are a must for cold shrink applications.

Components A and B are delivered ready to use in drums of 20 and 200 litres capacity. They can be pumped by means of standard metering equipment from these drums and mixing in a static mixer straight into the heated mold.

The mixing ratio is 1 : 1. At room temperature, mixtures of A and B components have a pot life of at least three days.
